2008 GMC Yukon Denali 6.2L maintenance
Not totally off topic. Getting a new TT next month... Coachman Apex 279RLSS, 5400 lbs dry...estimated 6000-6200 lbs. loaded.
Yukon Denali has 63500 miles with about 3000 towing since I got it a 44,000 miles. Tranny, engine and rr end fluids synthetic at 48,000 miles. All 50,000 servicing done at GM dealer service.
Two things....
1. it runs really good, but dealer service said replace plugs at 100,00 miles. Any views on the noticeable benefit in changing before towing the new trailer?
2. In this last cold spell...the air ride compressor would run for 2-3 minutes before it stopped. Anybody have experience with air ride component life? One blog suggested you can expect these to fail at 70,000 or so miles.
I'm going to have it checked out next week, but it's always good to get the experience of others.
